Sync AD and Custom Attributes from SQL to SharePoint User profile - FIM/MIM

We are working on the Sync process using FIM/MIM to sync AD and Custom attributes from sql server to SharePoint user profile.

So far I have done :

1. Created management agent for AD , SQL Server and SharePoint.
2. Created Custom Attributes in Metaverse.
3. Map and defined the attributes flow from SQL Server Agent to Metaverse.
4. Map and defined the attributes flow from Metaverse to SharePoint agent.

but after running the full sync cycle, custom attributes are not getting updated in sharepoint user profile.

please let me know if i am missing any steps.
